I'm just getting my feet wet with Spring and Spring Security, and I feel I must be missing something fundamental to the authentication configuration/process. After successful authentication, I need to redirect to one of several pages (sub-applications), depending upon how the user authenticated and their roles.

It was my understanding that I would have to write a custom AuthenticationSuccessHandler and override onAuthenticationSuccess(). I did that, but that class isn't getting called, so Spring Security just redirects to "/" by default I guess (where I get a 404). If I manually navigate to the proper page after authentication, it loads fine. Am I misconfigured?
Code:
<beans:bean id="myCustomAuthenticationProvider" class="com.company.MyAuthenticationProvider" >
<!-- this works fine -->
</beans:bean>

<beans:bean id="myAuthenticationSuccessHandler" class="com.company.MyAuthenticationSuccessHandler">
<!-- This never gets called -->
</beans:bean>

<beans:bean id="myAuthenticationEntryPoint" class="com.company.MyAuthenticationProcessingFilterEntryPoint">
    	<!-- This just appends to the querystring -->
   	<beans:property name="loginFormUrl" value="/login.html"/>
    	<beans:property name="forceHttps" value="true"/>
</beans:bean>

<beans:bean id="customAuthenticationProcessingFilter" class="com.company.MyAuthenticationProcessingFilter">
	<!-- this invalidates existing session before calling super.attemptAuthentication(...) -->
	<beans:property name="authenticationManager" ref="authenticationManager" />

<!-- Is this line configured wrong??? -->
	<beans:property name="authenticationSuccessHandler" ref="myAuthenticationSuccessHandler" />

	<beans:property name="allowSessionCreation" value="true" />
</beans:bean>

<authentication-manager alias='authenticationManager' >
	<authentication-provider ref="myCustomAuthenticationProvider" />
</authentication-manager>
...
<http auto-config="false" entry-point-ref="myAuthenticationEntryPoint" 
    		authentication-manager-ref="authenticationManager">
        
  		<custom-filter ref="customAuthenticationProcessingFilter" position="FORM_LOGIN_FILTER" />
